基于方位-能量的海底声学参数估计方法研究

估计海底声学参数并应用的方法有很多种,但由于过程复杂、投入较大,大都不容易实施.文中利用建立的方位-能量估计海底参数模型,在预先给出目标距离的情况下,使用遗传算法估计海底声学参数.这使得潜艇自身的声纳既可以用于在平时训练中积累海区海底声学参数又可以在战时直接使用这些参数为作战服务.这样海底声学参数的估计与应用有机的结合为一个整体,使得整个过程简便快捷、易于实现.

Study on Estimating Method of the Geoacoust Parameters Based on Bearing-energy Model

There are many kinds of method to estimate the ocean bottom properties and apply them. Be- cause of the complexity and expenses, it is difficult to implement these processes. This article indicates that based on bearing - energy model if the target distance was given in advance we can estimate the ocean bottom properties by genetic algorithm. So we can accumulate the ocean bottom properties value and apply them by the same sonar system. The simplicity and speediness derive from the combing of estimating and applying of the parameters.
